Description
Our Ostarine and Cardarine stack puts Ostarine 25mg/mL and Cardarine 20mg/mL together as two bottles, so a study that needs all of them can be ordered at once. It’s intended for lab and analytical work only.
The compounds in the Ostarine and Cardarine stack
MK-2866 is ostarine, also called enobosarm or GTx-024, a nonsteroidal SARM first developed by GTx Inc. It binds the androgen receptor, but its structure isn’t based on testosterone, and in lab models it acts mainly on muscle and bone with much less activity in tissues like the prostate.
GW501516 (cardarine) is a PPAR-delta agonist developed by GlaxoSmithKline and Ligand in the 1990s. It’s often sold next to SARMs, but it works through a different receptor, one that switches on fat-burning genes in muscle.
Why these compounds are paired
The compounds in this stack don’t overlap: Ostarine is the most studied SARM, with human trial data on muscle wasting and Cardarine is a PPAR-delta agonist studied for endurance and fat burning in mice. Labs that want to look at more than one pathway in the same model often order them together, and buying them as a set keeps the batches matched.
Because each compound comes in its own container, you can measure them independently and change the ratio between experiments.
How the Ostarine and Cardarine stack works
Ostarine binds the androgen receptor in the cell’s cytoplasm. The receptor then moves into the nucleus and switches on androgen-responsive genes, the same basic route testosterone uses.
PPAR-delta is a nuclear receptor. When GW501516 binds it, it pairs with the retinoid X receptor and switches on genes for taking up and burning fatty acids, such as CPT1 and PDK4.

Research behind the Ostarine and Cardarine stack
The best-known study is a phase 2 trial by Dobs and colleagues, published in The Lancet Oncology in 2013. It tested enobosarm in 159 patients with cancer-related muscle wasting and reported more lean body mass than placebo.
Narkar and colleagues showed in Cell in 2008 that GW501516 combined with exercise or with AICAR raised running endurance in mice and shifted muscle toward slow-twitch fibers.

Measuring and storing the Ostarine and Cardarine stack
Every bottle is 30mL with a graduated 1mL glass pipette. Since the strengths differ, label which pipette belongs to which bottle:
- Ostarine at 25mg/mL: 1mL holds 25mg, 750mg per bottle
- Cardarine at 20mg/mL: 1mL holds 20mg, 600mg per bottle
PEG-400 is thicker than water, so draw slowly and let the pipette drain. Store the bottles capped in a cool, dry place out of direct light.
Ostarine and Cardarine stack certificate of analysis
The current certificates of analysis show Ostarine at 98.04% and Cardarine at 99.57% by HPLC. The testing is done by MZ Biolabs, an independent lab in Tucson, Arizona, which also checks identity by mass spectrometry.
The COA image is in the product gallery at the top of this page, so you can read the batch result before you order.
Why two tests? A sample can be very pure and still be the wrong compound. HPLC measures purity and mass spec confirms the molecular weight, so together they cover both problems.
If anything arrives wrong, the 60-day money-back guarantee covers it.
